  • the schedule module 112 may cooperate with the display module 118 to present input field 612 to receive additional training plan characteristics, such as a time characteristic. For example, in FIG. 6 , the user has entered 5 minutes into the field 612, indicating that the user anticipates implementing the training plan in 5 minutes.
  • the timing elements may be auto-filled based on statistics associated with the operator (e.g., the instructor or student) and/or the associated maneuvers. Such statistics may have other functions, including evaluation of an operator or maneuver, e.g., to determine how long a maneuver takes, trends, etc., thereby providing the efficient use an release of airspace.
  • the training plan characteristic defined in input field 612 is associated with the training plan by the schedule module 112 and may be presented on the visual display 200.
  • the time characteristic 702 is displayed on the visual display 200.
  • the schedule module 112 may cooperate with the display module 118 to present menu 712 to receive additional training plan characteristics, such as planned maneuver characteristics.
  • the user may select from a menu 712 of potential maneuvers (e.g. simulated engine failure, slow flight, stalls, etc.), thereby creating a list or schedule of planned maneuvers.
  • the schedule module 112 associates the maneuver characteristics with the training plan, and the display module 118 maintains the training plan symbol 410 on the visual display 200, as depicted in the example of FIG. 8 .
  • One or more training plan characteristics representing the scheduled training plan may be presented, including the altitude characteristics 604, 606 and/or time characteristic 702.
  • additional training plan characteristics may be presented to the user, such as the training plan name and maneuver characteristics.
  • the training plan symbol 410 may have a numerical designation, particularly if the user is creating multiple training plans (or multiple segments of a training plan). In such an example, the numerical designation of the training plan may indicate the intended order of execution of the training plans.
  • the training plan symbol 410 is designated as the first training plan (e.g. with a "1").
  • the schedule module 112 does not enable a user to create a training plan that interferes with an existing training plan.
  • the schedule module 112 may have airspace planning algorithms that identify conflicts and will prevent interference and/or alert the user to interference.
  • the schedule module 112 may enable the creation of a training plan in a practice zone with an existing training plan, if the characteristics of the training plans do not conflict. For example, in some embodiments, multiple training plans may be created for a single practice area if the altitudes or times do not overlap. Additional conflict consideration may include inappropriate altitudes for the aircraft service ceiling, airspeed, etc. In such an instance, the schedule module 112 may restrict the available characteristics for selection presented to the user during creation of the training plan to avoid interference.
  • a safety margin may be incorporated into the review of potential and scheduled training plans by the schedule module 112. Accordingly, the system 100 may protect the operator from selecting occupied or reserved airspace, choosing inappropriate altitudes or areas, and/or choosing airspace in which training is not allowed. Further, the schedule module 112 may consider real time flight or navigation information regarding potential interference. For example, the schedule module 112 may not allow reservation of a practice area by an aircraft that is 10 minutes away from the practice area that is scheduled for use in 5 minutes by another aircraft. Generally, the schedule module 112 may consider updates by the user by releasing airspace or adjusting time or altitude, or further could be based on actual aircraft taxi time (e.g., a late taxi means late to the practice area).
  • the system 100 may monitor input data and update the visual display 200 for the user. For example, based on information from the ownship module 116, the schedule module 112 and/or display module 118 may update the appearance of the navigation map 210 and training plan symbols 230-233, 410, as appropriate. Although depicted as a static display, the visual display 200 may be centered on the aircraft symbol 802 and be updated based on aircraft position. Further, the visual display 200 may be rendered as a north-up, track-based, or heading-based orientation. In some embodiments, the system 100 may monitor the other training plan characteristics and/or the position of the other aircraft to remove the other training plan symbols 220-223 upon completion of the respective training plans.
  • the schedule module 112 and/or display module 118 may update or remove the ownship training plan symbol 410.
  • the system 100 may use an ADS-B identification to link a training plan to a target sensed by another aspect of the aircraft.
  • FIG. 8 additionally depicts an aircraft symbol 802 on the visual display 200 that represents the current geographic position of the aircraft relative to the navigation map 210.
  • the position of the aircraft symbol 802 relative to the training plan symbol 410 may additionally indicate the position of the aircraft within the practice zone. As such, if the aircraft symbol 802 approaches the boundary or goes outside of the boundary of the training plan symbol 410, the user may take action to return to the designated practice zone.
  • the visual display 200 provides advisory or warning indicia for the position of the aircraft relative to the training plan. For example, if the aircraft symbol 802 is proximate to or outside of the boundaries of the training plan symbol 410, thus indicating that the aircraft may be approaching or exceeding the geographical limits of the training plan zone), the appearance of the training plan symbol 410 may be modified. For example, when the aircraft symbol 802 is proximate to the boundary of the training plan symbol 410, the training plan symbol 410 may be rendered in a yellow color, or when the aircraft symbol 802 is outside of the boundary of the training plan symbol 410, the training plan symbol may be rendered in a red color.
  • the control unit 110 may initiate similar indicia for approaching or exceeding the time and altitude characteristics of the training plan.
  • the color or other symbology associated with the training plan symbols 220-223 may reflect a number of different types of information. For example, a green color may indicate that the associated aircraft is presently implementing the training plan in the area indicated by the training plan symbol 220-223. A blue color may indicate a future use of the training plan in the area indicated by the training plan symbol 220-223. Similarly, the color may reflect advisory or warning indicia may also be presented for other aircraft. For example, if the aircraft associated with training plan symbol 221 (or another aircraft that did not reserve the respective training plan area) is positioned within the area represented by training plan symbol 220, the training plan symbol 220 may be presented with a yellow or red color to indicate that an aircraft is intruding into the airspace of another training plan.
  • the user may modify an existing training plan by selecting the training plan symbol and editing the characteristic fields discussed above. Additionally, the user may create additional training plans, for example, by selecting an additional zone on the navigation map 210 and providing user inputs to the system 100 similar to those discussed above. For example, with reference to FIG. 9 , the user may create a second ownship training plan symbol 910.
  • the system 100 may provide a representation of the separation 912 between the zones of the training plan symbols 410, 910 in either time or distance to facilitate an ordered execution of the training plans represented by the two training plan symbols 410, 910.
  • the separation 912 may be determined as a transit time between training plans as a statistic value represented by the arrow.
  • the message module 120 of the control unit 110 may generate a message containing information associated with the training plans.
  • the communications unit 160 may send such messages to a command center or other aircraft.
  • the training plans created by the user may be presented to other aircraft as other aircraft training plans for the consideration and evaluation of other users that are also creating and/or executing training plans.
  • the position and appearance of the images and other symbology on the visual display 200 may be dynamically generated by the control unit 110 on the display device 140.
  • symbology are presented in FIGS. 3-9 , any suitable type or manner of symbology may be used, and in various embodiments, one or more of the types of training plan symbology may be omitted and/or supplemented.
  • the system 100 may be considered shared or "crowdsourced" across all user or affiliated users within an area.
  • each aircraft may create a training plan for the system to present on a common display for all such training plans.
  • the system 100 may be implemented as an "application" on a mobile device.
  • embodiments disclosed above are typically used for training flights within a geographic area, and not for ordinary flight traffic (e.g., flight plans for traveling from point A to point B).
  • the visual display 200 may implement or present a timeline or timelapse function, for example as a timeline slider, that may be used to view an integration of training plans in space and time into the future.
  • exemplary embodiments may additionally include a method for displaying practice airspace information for an ownship aircraft and other aircraft in the area.
  • the method may include displaying a navigation map view of a surrounding area; receiving and displaying training plan information for other aircraft in the area; receiving user input selecting a location and characteristics for an ownship training plan; displaying training plan symbology on the navigation map view; and updating the navigation map view based on updated flight information and/or upon modification of the training plans.
  • exemplary embodiments enable management of practice airspace information in a manner that is intuitive and graphically integrated with other types of flight information.
  • exemplary embodiments provide such symbology as a quick snapshot of the position and characteristics of training plans in an area.
  • symbology facilitates flight crew or operator situational awareness and vehicle control, which reduces pilot or operator workload and navigation errors, and thus results in increased aircraft and/or navigation safety.
